How high have you reached?

[WildBillKelsoe]

Post tracks of how high you have reached! Do 1/2 IBR and dive down, Yeager style!!!

 

 

go to 19min 38 secs!!!

Maybe 25,000 ft. No track. This was with a keyboard, starting in the air at max speed. The P-51 doesn't like keyboards.

 

The dive I have done though. I may or may not have lost a wing and/or blacked out.

[ErichVon]

Operational bombing runs in real life were 18,000 feet to 42,000 feet. Just saw that the other night, wee morning hours, on "Great Planes" on the Military Channel.

 

In Aces High:

the B-17 will achieve 43,000 feet but settles in at 42,000 feet. After a run I always escaped high. P-47, Spits, and some of the German planes can get that high, in that game/sim. Few pilots know how to fly combat that high, the air is so thin.

 

I just took the DCS World P-51D, Single Player, version beta 1.2.0 to 37,000 feet, but it is not very comfortable at that altitude. Might be able to squeeze 38,000 feet. If you take the time to wide open speed on the level, zero climb, then climb up, might achieve higher altitude. Stall buffeting at 37,000 feet about 140 mph indicated. I was riding wide open. Doesn't look like WEP's time limit on max is implemented, yet. I was strictly instrument flying. Manifold pressure was 23, RPMs 30, oil temp 85 degrees Celsius, coolant temp 110 degrees Celsius, carb temp bottom of left scale. Started out in Single Player in a stock mission from Batumi with full left and right fuel tanks. At 37,000 feet I was not quite half-way empty; I manually switched tanks to equalize them. Supercharger was set to Auto. Setting trim much above 30,000 feet didn't seem to help much. I map all 3 axis trimmers.

I have not stayed in a Holiday Inn Express in quite awhile so my piloting skills reflect this, sorry.

 

A better landing from 37K . Same as above, but jumped in on the descent and landed it:

I don't know what the engineering specs state.

 

I fetched some Aces High spec sheets for the P-51D and left a couple links here:

http://www.hitechcreations.com/component/option,com_ahplaneperf/Itemid,221/view,ahplaneperf/index.php

 

I didn't know if this DCS P-51D will lock up over 500 mph in a dive. I backed off throttle manifold pressure and RPM wheel to all the way back. In about a 45 degree dive, 1st Mediafire link. At about 400 mph in the 20,000 feet range started to high speed buffet. I then maxed throttle and rpm, made the mistake of an abrupt move upwards and tore off both wing tips at 450 mph at about 12,000 feet. I tried to save it but not. Waited too long to bail-out and ran out of time and air---POOF. This plane is not Aces High, LOL!

 

Dogfighting with the AI guy in Single Player, at various altitudes, speed, and angle of attack, I encountered stall buffeting 200 or 300 mph. I am not a real life pilot, but I know those 3 factors encourage how a plane operates positively or negatively and also the trim attitudes will change.

 

The only WWII prop plane I am aware of that was great at high altitudes was the German Focke-Wulf designated Ta-152H. In Aces High I got her to 49,000 feet, but I also stalled it and did not recover until about 3,000 feet and I tried everything I could think off to quit spinning. Like DCS World, the Aces High pilot will blackout or redout depending if positive or negative G's. Also, I think any plane will flat spin given the incorrect opportunity and man does that altitude meter spin fast. I usually just back off on the throttle and rpm's and coast it down. Also this DCS P-51D you can put the mixture control to IDLE and it will coast a bit slower I think. The 1st notch of flaps will engage down around 400 mph. But I was deliberately trying to lock up the controls in a dive.

 

How to stop the outside view rotational oscillation? It is called camera jiggle. To toggle on/off : LShift + J

that's great, but, track?:P:P

[ErichVon]

I'm not into the video stuff, but I did save the track in my REPLAY within DCS World 1.2.0, P-51D 1.2.0 .

 

Someone please give me some instructions how to post my .trk file here to my message #3 above, or where to find the info.

Edited September 16, 2012 by ErichVon

[WildBillKelsoe]

I'm not into the video stuff, but my DCS is still up, wing tips off, and burning, 450 mph.

 

Give me some instructions how to obtain track and how to post it here.

 

I will leave my experiment up and wait for your or a reply.

 

 

with the sim up, go to C:/Windows/Temp/DCS/ and copy LastMissionTrack.trk to a folder. If it's over 5 mb, you're gonna have to use offsite host, like mediafire. If under 5 mbs, post new reply, click go advanced, manage attachments, and browse to the file. let it upload, when finished, you'll have it at the same window with size and the editorial page will contain the file at the manage attachments portion. click post and you're good to go.

[joey45]

I've gone over 9,000............

 

99% of you will not get that..

I watched the video. Have seen it before. All those military dressed guys are actors. The bald headed guy is Lee J. Cobb. The cartoons were probably made by Disney. They militarized Hollywood during WWII. A lot of it for training films.

 

I noticed on landing the video states to set the mixture to full rich.

 

I will try that.

 

I just come in by feel, back off on the throttle, leave the rpm's high just before I encourage the Mustang to stall. I try to settle short of the threshold just a few feet over the runway, stick is in my lap and let it stall down below 100 mph. I do not touch the brakes until I get ready to turn off the runway. I think the Spits are the touchiest to land, such narrowness between the wheels.

 

In my videos, why I keep pulling the throttle back is to see the altimeter and what altitude I am at. I need to set an offset in-cockpit view.

 

I just recently installed the P-51D version 1.2.0 on Saturday September 15, 2012. The controls still need some fine tuning.

Lol I got it.

 

I've only gotten as high as 25000

[Blaze]

I've reached the 40's, it takes a long-@$$ time though and careful engine management. But definitely possible in the sim.

Where 2 see scouter in airplane?

[504smudge]

I get to 17.000 ft and after that I cant seem to get enough speed/power to climb, the stang just starts to wallow and bleeds below 150 mph and I cannot push her any higher, any tips?

[Suchacz]

The "navigation mission" in default campaign forces you to fly to 35,000 ft.

Smudge - Sounds like you're still carrying your drop tanks? If max height is the aim you need a clean machine:)

[Ala13_ManOWar]

I got, don't remember exactly, 38-40k Yeager style as you said :), it was in Viazma cold start mission (not every "day", temperature, pressure, you can reach what you want). No track. Hard but you can reach easily with time. At that height maneuvering is difficult, you have to move stick carefully and she's like very overweighted. I did to probe supercharger stage change, and then go ahead higher. When in top I dived hard to probe high speed controls and Vne, but although I wasn't in a 90º dive (may be 45-60º) really I was unable to overspeed her. Then landed with no further notice. (it happened in a 1.2.1 game).

 

S!

[ophiuchus]

35000 ft in navigation mission with blower set to low, but tried just a minute ago in "cold start vaziani" and with blower set to auto I managed to reach about 23000 and after that engine died (35" MP and 2500 RPM, temperature kept between 60 and 80 °C).

RL P-51 D should reach :

 

4.Time to climb to service ceiling, war emergency power

(3000 RPM and 67") (41600') - 28 minutes

 

 

And from Mustang IV ( D) RAF chart:

 

Service celling:

max weight - 40 500 ft

mean weight - 41 500 ft

28 minutes.

[Kwiatek]

I tested DCS P-51 ( full wing fuel tanks from deck) and i reached 12 300m / 41 000 ft - so it is very accurate results comparing to RL data.

Nice going!

 

I haven't tried for ceiling yet, but have been going for long range and checking my understanding of how to keep the fan going for the duration:)

 

So's we don't confuse anyone still learning this beast (myself very much included) and to check I'm using the right settings... you needed to drop them there tanks around the 15-20K feet mark right?

 

Gotta try going all the way upstairs - highest I've done was about 32K feet on a long range job.

[VIMANAMAN]

Doh! Sorry Kwiatek!

 

( full wing fuel tanks from deck)

 

Just re-read your post and see you clearly said wing tanks, not drop tanks - sorry for the stupid Q. Glad you didn't drop your wings at any point!

 

Anyone managing to get over 20K with drop tanks? I've been trying to find WWII details of flight profiles for long range escort missions but the best I can find is passing remarks in documentaries - highest reference I've seen was 20K ft (which I can't match).

 

I guess like us they did a very protracted climb up to <20K until they'd used and then ditched they're tanks?

[504smudge]

what RPM and Manifold pressure do you maintain once the blower kicks in? I find trying to maintain 2600rpm and 46 Hg causes the engine to pre-detonate and leads to a seized engine quite quickly, i cut back on the RPM to about 24000rpm and everything seems stable but it feels like the stang has no power left to climb, that is with a clean bird and about 3/4 full tanks.

 

also to maintain 170 mph (best climb speed) after 15.000ft i almost always have a decent angle, and to keep about 2.5 to 5m/s up i drop below 150mph and start to wallow/stall.

To reach maximal altitude 3000 is necessary because the blower boost pressure depends on rpm.

If you do not want the fastest climb you can use 46 2700 but after you rich max throttle altitude for high blower you have to increase rpm up to 3000 to maintain boost.

Hi (504)smudge,

 

Sorry I assumed you had tanks on - I guessed you were having the same problems I was having!

 

If you can fast forward through this in HD you should be able to read the numbers that work for me.

 

But they are not optimal to the best of my knowledge - And, I wasn't trying to go high, (but long), but it'll get you through the 15-30k ft range and then it sounds like Yo-Yo's advice should be applied (if not a bit before 30K ft).

 

That's good advice as ever Yo-Yo - I didn't know that.

 

 

This Vid is more of a record for me - it's like watching paint dry :music_whistling: - Hope it helps a bit anyway.

I reached 39 with 60ish% fuel. Going to have to try going rich max and see if that makes a difference. It seems that climbing at 170 is not possible due to overheating.
